I take 2,000 IU of vitamin D (as vitamin D3). Earlier this year I was found to be very deficient in vitamin D, I went on a treatment of 20,000 IU for 2 months then I was put on 2,000 IU per day for the rest of my life. When I got pregnant I just kept taking the same amount. I have not discussed that with my gynecologist but my regular doctor told me it's very important for pregnant women to get enough vitamin D during pregnancy.

I am not suggesting that you start taking high levels of vitamin D (not at all) but I encourage you to speak about that with your doctor, he can do a quick blood test to see what's your level of vitamin D.
Otherwise the only good way to get natural vitamin D is to spend at least 20 mns/day in the sun - if you're lucky to live in a warm place all year round.

As for calcium, I do not drink much milk but I eat a lot of cheese and yogurts, so for me that's probably fine.

Very good question, and I concur with the others that Vitamin D is very important in pregnancy. More and more health care providers are coming to believe that we need at least 2,000IU per day, especially in northern climates. And yes, a simple blood test will reveal whether you are deficient, so ask your health care provider about it for sure!

Vitamin D is essential for many facets of fetal development, including teeth, eyes and brain.

I have been reading some on the subject. It does seem that most Americans are vitamin D deficient, it doesn't help that we have become so afraid of the Sun, even with its benefits. It seems Vitamin D can help with a healthy pregnancy and the future health of the child. Check this out and definately talk to your doc.
